A human readable textual description of the custom error is available in this property. You can assign a new value if you wish. Reading the property yields the value that was passed in the description argument to the constructor function unless it has been changed since then.

Warnings:

• The ECMA standard describes this property as Error.message. Netscape 6.0 claims to be completely compliant and therefore should support this property.

• MSIE supports the description property which is functionally identical.
